x86, kvm: Call restore_sched_clock_state() only after %gs is initialized
s2ram broke due to this KVM commit: b74f05d61b73 x86: kvmclock: abstract save/restore sched_clock_state restore_sched_clock_state() methods use percpu data, therefore they must run after %gs is initialized, but before mtrr_bp_restore() (due to lockstat using sched_clock). Move it to the correct place.
